'One common thread runs through the many different stories of denial: people, organizations, governments or whole societies are presented with information that is too disturbing, threatening or anomalous to be fully absorbed or openly acknowledged. The information is therefore somehow repressed, disavowed, pushed aside or reinterpreted. Or else the information 'registers' well enough, but its implications - cognitive, emotional or moral - are evaded, neutralized or rationalized away.'
Stanley Cohen (2001) States of Denial: Knowing about atrocities and suffering. p. 1.
'Denial is always partial, some information is always registered. This paradox - or doubleness - knowing and not knowing is the heart of the concept. It creates what Wurmser nicely calls 'Pseudo-stupidity.'
